- What is the main cleaning agent used to decontaminate patient equipment? Hydrogen Peroxide & Peracetic Acid Hydrogen peroxide is supplied either as a ready-to-use 3% solution or as a 30% aqueous solution to be diluted to 5-10 times its volume with sterilized water. However, such 3-6% solutions of hydrogen peroxide alone are relatively slow and limited as germicides.
